|Winter Burn on Blue Atlas Cedar|
This browning of the needles or "winter burn" should correct itself once the weather starts to warm and water is able to get to the cells of the plant and once again activate the chlorophyll within. If the tree is well established it should most likely fully recover and start to push out new growth as the temperatures rise. If the tree looks severely damaged then getting water to the roots and deep root feeding in early spring are recommended to help the plant to recover. Deep root feeding is a controlled fertilization process that supplies immediate beneficial nutrients directly to the root system to give it a boost. There is also a product on the market called PHC BioPak Plus which contains micro nutrients and beneficial bacteria to help the roots to absorb nutrients and help plants in stress.
Just an added note that the needles of Cryptomeria japonica do turn a bronze color in winter which is perfectly normal. I have found that with the severe weather there has also been an increased number of fallen branches and browning of needles and branches; however, the winter winds seem to be nature's way of giving the trees a good cleaning out. In the spring sunlight will be able to reach the inner portion of these evergreens and cause the trees to push out new growth.
|Skylands Oriental Spruce|
There may be some winter burn and dead branches on your Oriental Spruce as well from the winter's winds and snow. Spring is the best time to cut out any dead branches and the browned needles should recover once water moves back into the cells and chlorophyll causes the plant to re-gain its color.
It is not recommended to spray the above-mentioned trees with anti-desiccant because it has been known to change the beautiful color of these trees. When in doubt always ask a tree professional.
Many evergreens do go through a natural shed of their inner needles approximately every three years in order to make room for new growth. Once the harshness of the winter winds diminish and spring arrives new growth will eventually push out and restore the natural beauty of your evergreens.
As Always...Happy Gardening!
